ABM1

    Explanation
      A basic mapping support (BMS) service is requested by a task associated with a terminal that is not supported by BMS. The request is not a routing request.

    System action
      The transaction is abnormally terminated with a CICS transaction dump.

    User response
      Do not use terminals not supported by BMS for applications using BMS services.

      Check the terminal type and model number. Confirm that it is a terminal that is not supported by BMS. A list of terminals supported by BMS is given in the Developing CICS Applications. Check that the resource definition for the terminal accurately describes the physical terminal.

    Problem determination
      At the time of the abend, register 11 addresses the TCTTE, and TCTTETEA and register 6 address the TCTTE extension, TCTETTE.

      Relevant fields are:

TCTTEDDS  the device dependent suffix.
TCTTEMSS  the map set suffix.

        Analysis: DFHRLR tests the device dependent suffix and the map set suffix in the TCTTE extension. If both of these are zero, the terminal is not supported by BMS and DFHRLR abends the task with the abend code ABM1.

Register  Label     Description

R4=       RLRSFXCK  TCTEDDS=X'00' and
                    TCTEMSS=X'00'.
@TCTTETE            The device dependent suffix
                    and the map set suffix have
                    loaded into the lower two
                    bytes of register 3 by the
                    subroutine RLRSUFXS.
